Add hardhat-ethers to the mocha+ethers devDependencies

[alcuadrado]

The reason this change is needed is because the files generated by TypeChain import @nomicfoundation/hardhat-ethers/types. That means that users need to install that directly, or it won't work with pnpm.

Pull Request Overview

This PR adds @nomicfoundation/hardhat-ethers as a direct dependency to address TypeChain-generated file imports. TypeChain generates files that import @nomicfoundation/hardhat-ethers/types, which requires the package to be explicitly installed for compatibility with strict package managers like pnpm.

Key Changes:

• Added @nomicfoundation/hardhat-ethers v4.0.2 to devDependencies in the mocha-ethers template

Files not reviewed (1)

• pnpm-lock.yaml: Language not supported
